Could someone tell me if the manifold end of the cat has studs or bolts? Also what size head are they?
Just want to make sure I have correct tools before starting.

Think my cats cooled enough now!! Anybody any ideas on initial question please?

Studs in the manifold, special nuts with helicoil thread inserts.

Use a sparkplug socket, one of the hexagonal type, dont use a bi-hex socket. iirc its 18mm AF

try to get some penetrant spray such as plusgas or rust flash into the nuts to avoid shearing the studs.

Thanks very much. I have eveything I need. Off to change

Forgot to say... the above applies to V6. 4 pot have bolts

All sorted. The top nuts came off no trouble. The non GM cat sounds like a bag of pooh. I was advised by james but I needed it done for the weekend. I'll keep an eye out for a 2nd hand nearside cat.
